After using Ubuntu for a while, I realised that Ubuntu GNOME is rich in graphical interfaces, which consumes a lot of resources from my laptop, which is kind of old.

What i want to do is to switch to Xubuntu if it's possible or any other suggested UI that is simpler in graphical terms.

Is it possible and how to do it?

P.S suggestions of other interfaces are welcome!

Edit: Oh sorry, didn't read carefully. I was thinking of the normal Ubuntu. Most of the steps should apply though, as Unity is based on GNOME 3.

How To Install XFCE alongside Unity (the enviornment that comes with Ubuntu)

It's recommended to add another user so data doesn't corrupt. (Skip if you don't want to)

Open System Settings (unity-control-center) and click User Accounts. Click the Unlock button on the top right and type in your password as needed. Then, click the + button on the bottom left and select Administrator. Then, choose a Username and Name for the account.

Log out of the account you are in right now and Log In to the account you just made.

Install XFCE

It's recommended to update your sources. Open Terminal with Ctrl + Alt + T and type

sudo apt-get update

Then, install XFCE!

sudo apt-get install -y xfce4 xfce4-goodies

Log out, click the Ubuntu logo over the account name, and click XFCE.

Another way

You can download Xubuntu from the official website, here

Hope this helped!
